' To @ZZ/whom it may concern:

Be it known that .i Lfltnssnnn HUFF, a citizen of the United States, residing at Der' troit, Michigan, have invented certain new andk useful Improvements inOil-Guards, of

which the following exact description.

This invention relates to oil guards, more particularly adapted for use in connection 1o -with well known or any other suitable means for utilizing the centrifugal force of a rotating lcrank. `shaft in a motor driven vehicle to throw oi from `the shaft the j oil which leaksy bearing. j y v `One object of theinvention is to provide oil-catchingmeans so located as to` prevent the yoil from dropping onto the shaft. j

Another object is to compel the `oil to flow `away from the outer wall of'thehousing around the throw-oimeans fassaid oil approachesthe joint between theupper and ,lower halves of the housing. j p i Still another object is to provldemeans which bridge the housing -j ductthe oil past said joint, i l

` Other objects are to provide practical and efficient means for conducting oil from a bearing. i l Thesebeing amongthe objects of the present invention, y,the

of parts to be hereinafterdescribed and then claimed with reference to the accompanying drawin s illustrating a desirable embodimento the invention and in which- Figure 1 is a. sectional view partly in elevation showing the rear bearing for a crank v, shaft, provided with the present improve `ments; Fig."2 isa section on the line.22 Fi `1 in the direction of the arrow; Fig.

p between them, and a chamber withinthem within which is located a throw-off ring or ridge 16 extending annularly around and upon the shaft 12. v At the bottom of the well of thefhousing chamber there is located a drain hole 17 adapted tof` conduct yoil into the main yportion of the oil-pan. The oil whichiows away from the bearing 11 is thrown by the centrifugal force of the rotating shaft 12 into the housing chamber,

and drops thereinto into the rbottom o the well and {iowsout through the drain hole 17.l The oil thrownoii from the "ring or ridge 16 either strikes against the upper tion 14. The oil which is thrown against the upper section of the housing will naturally run down and would fall either upon the shaft 12 or appearl the' housing, where it could escape "to the outsidel of the said housing. The above described parts are well known 1and the presing the objections thereto. y

Under the present invention oil-catching or intercepting means are 'provided which ,are so located within the housing 13, 14 as to coact withthe throw-off ringl or ridge 16 vincon'ducting oil away from lthe bearing. Preferably the said 'oil-catching `orl 'intercepting-means comprise a trough-member 18 an'ge 19 which preferably extends through-- thesame constitutin Y aniarc of 180 degrees,

means for supporting the trough-member o the .inner wall of the upper section-oi the housing. Usually said back flange'is welded to the housing section 13 in such' positionas `to closely encompass the upperportion of the shaft l2. In' other-words, 4liange is positioned upon the housin fright ,angles to the longitudinal axis o [shaft and its inner curve follows closely the surface of the'shaft.` The? of the flange 18 are widened `as shown in Figs. 2 and 4, so as to provide widened end portions QOiwhich extend'below the joint 15. Trough-member 18 is urthermoreprovided with a catch or intercepting lip .21 which is section 13 of the housing orthclower sec-" at the' joint 15 ofent invention relates .to'means for overcomwhich `is composedm a metal stamping conthe said back they lower extremities preferably curved lin cross-section and conerablythe said catch lip is 21 is of less dimension than I ping of said oil thereon.

- being cated above the joint 15. channel is formed between the said lip 21 and the adjacent wall of the housing. Prefso curved as to gradually merge into the flange 19, the vplane of its edge being substantially paral- .the catch lip 21 the extremities of the trough-member are provided wide fiangel or bridge portions 22 which are disposed at' right angles to the end portions 20.7 'The lo-wer ends of the trough-member yin cross-section, they responding corners of the housing. As the vertical section of the flange 19 and the lip the horizontal dimension of the end portions 20, and as the ,end `portions 20, 22 fit into the corners of the housing while the edge of the lip 2l is spaced away from the wall of the housing, it will be seen that the curve of the edge kof the lip is of less radius than the curvesof the tions 22.

At 23 the ends of the lip 21 are joined together with the upper ends of the flange or bridge portions 22, byI suitably bending up the metal stamping.

- It will be seen that in'practice the oil which is thrown outwardly into the upper part-of the housing, will be caught by the lip 21 and will flow to both sides in the trough 18, from whence it will be carried by the connecting portions 23 along the inner walls of the body'portions 22 which extend past the joint 15, and will then drop into the well of the housing. v f

It is obvious th-at the invention is suscep'# tible of modication, as parts may be omitted, added and -substituted without departtion as expressed in the claims.

What I claim as new is v 1. In a device of the class described, the combination of a housing, a shaft journaled therein and provided within said housing with centrifugally acting oil throw-ofi means, and vcatching means fitted inside of said housing for intercepting the oil thrown oli' and guarding said shaft against droping from the scope andspirit of the inven- 2.
